5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)), including Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate. Avoid the use of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) supplements, including Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) based nonprescription antacids, concurrently with Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate.

An overdose of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) levels twice weekly. Should hypercalcemia develop, reduce the Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia

More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate therapy.

Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.

Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate on the progression of vascular or soft tissue calcification has not been determined.

Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate; all cases resolved upon lowering the dose or discontinuing treatment.

Chemical Structure

12 CLINICAL PHARMACOLOGY

Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Cal-Mag; Vitamin D; Zinc ) resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.

12.2 Pharmacodynamics

Orally administered Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate.

14 CLINICAL STUDIES

Effectiveness of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate solid oral dosage form.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Carbonate)) levels are also presented.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Citrate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Citrate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Citrate)) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Citrate)) increased 9% during the study mostly in the first month of the study.

Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Citrate)) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.

The phosphate binding effect of Cal-Mag; Vitamin D; Zinc (Calcium (Calcium Citrate)) acetate is shown in the Table 3.

Magnesium (Magnesium Citrate):



Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Sulfate

Injection, USP

Ansyr Plastic Syringe

Rx only

Hospira Logo

DESCRIPTION

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Sulfate Injection, USP is a sterile solution of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate heptahydrate in Water for Injection, USP administered by the intravenous or intramuscular routes as an electrolyte replenisher or anticonvulsant. Must be diluted before intravenous use. May contain sulfuric acid and/or sodium hydroxide for pH adjustment. The pH is 5.5 to 7.0. The 50% concentration has an osmolarity of 4.06 mOsmol/mL (calc.).

The solution contains no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and is intended only for use as a single-dose injection. When smaller doses are required the unused portion should be discarded with the entire unit.

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Sulfate, USP heptahydrate is chemically designated MgSO4 - 7H2O with molecular weight of 246.48 and occurs as colorless crystals or white powder freely soluble in water.

The plastic syringe is molded from a specially formulated polypropylene. Water permeates from inside the container at an extremely slow rate which will have an insignificant effect on solution concentration over the expected shelf life. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the syringe material.

CLINICAL PHARMACOLOGY

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) (Mg++) is an important cofactor for enzymatic reactions and plays an important role in neurochemical transmission and muscular excitability.

As a nutritional adjunct in hyperalimentation, the precise mechanism of action for Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) is uncertain. Early symptoms of hypomagnesemia (less than 1.5 mEq/liter) may develop as early as three to four days or within weeks.

Predominant deficiency effects are neurological, e.g., muscle irritability, clonic twitching and tremors. Hypocalcemia and hypokalemia often follow low serum levels of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)). While there are large stores of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) present intracellularly and in the bones of adults, these stores often are not mobilized sufficiently to maintain plasma levels. Parenteral Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) therapy repairs the plasma deficit and causes deficiency symptoms and signs to cease.

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) prevents or controls convulsions by blocking neuromuscular transmission and decreasing the amount of acetylcholine liberated at the end plate by the motor nerve impulse. Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) is said to have a depressant effect on the central nervous system (CNS), but it does not adversely affect the woman, fetus or neonate when used as directed in eclampsia or pre-eclampsia. Normal plasma Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) levels range from 1.5 to 2.5 mEq/liter.

As plasma Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) rises above 4 mEq/liter, the deep tendon reflexes are first decreased and then disappear as the plasma level approaches 10 mEq/liter. At this level respiratory paralysis may occur. Heart block also may occur at this or lower plasma levels of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)). Serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) concentrations in excess of 12 mEq/L may be fatal.

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) acts peripherally to produce vasodilation. With low doses only flushing and sweating occur, but larger doses cause lowering of blood pressure. The central and peripheral effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) poisoning are antagonized to some extent by intravenous administration of calcium.

Pharmacokinetics

With intravenous administration the onset of anticonvulsant action is immediate and lasts about 30 minutes. Following intramuscular administration the onset of action occurs in about one hour and persists for three to four hours. Effective anticonvulsant serum levels range from 2.5 to 7.5 mEq/liter. Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Sulfate Injection, USP is suitable for replacement therapy in Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) deficiency, especially in acute hypomagnesemia accompanied by signs of tetany similar to those observed in hypocalcemia. In such cases, the serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) (Mg++) level is usually below the lower limit of normal (1.5 to 2.5 mEq/liter) and the serum calcium (Ca++) level is normal (4.3 to 5.3 mEq/liter) or elevated.

In total parenteral nutrition (TPN), Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate may be added to the nutrient admixture to correct or prevent hypomagnesemia which can arise during the course of therapy.

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Sulfate Injection, USP is also indicated for the prevention and control of seizures (convulsions) in pre-eclampsia and eclampsia, respectively.

CONTRAINDICATIONS

Parenteral administration of the drug is contraindicated in patients with heart block or myocardial damage.

WARNINGS

FETAL HARM: Continuous administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate beyond 5 to 7 days to pregnant women can lead to hypocalcemia and bone abnormalities in the developing fetus. These bone abnormalities include skeletal demineralization and osteopenia. In addition, cases of neonatal fracture have been reported. The shortest duration of treatment that can lead to fetal harm is not known. Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate should be used during pregnancy only if clearly needed. If Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate is given for treatment of preterm labor, the woman should be informed that the efficacy and safety of such use have not been established and that use of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate beyond 5 to 7 days may cause fetal abnormalities.

ALUMINUM TOXICITY: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Parenteral use in the presence of renal insufficiency may lead to Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) intoxication. Intravenous use in the eclampsia should be reserved for immediate control of life-threatening convulsions.

PRECAUTIONS

General

Administer with caution if flushing and sweating occurs. When barbiturates, narcotics or other hypnotics (or systemic anesthetics) are to be given in conjunction with Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)), their dosage should be adjusted with caution because of additive CNS depressant effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)).

Because Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) is removed from the body solely by the kidneys, the drug should be used with caution in patients with renal impairment. Urine output should be maintained at a level of 100 mL or more during the four hours preceding each dose. Monitoring serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) levels and the patient's clinical status is essential to avoid the consequences of overdosage in toxemia. Clinical indications of a safe dosage regimen include the presence of the patellar reflex (knee jerk) and absence of respiratory depression (approximately 16 breaths or more/minute). When repeated doses of the drug are given parenterally, knee jerk reflexes should be tested before each dose and if they are absent, no additional Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) should be given until they return. Serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) levels usually sufficient to control convulsions range from 3 to 6 mg/100 mL (2.5 to 5 mEq/liter). The strength of the deep tendon reflexes begins to diminish when Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) levels exceed 4 mEq/liter. Reflexes may be absent at 10 mEq magnesium/liter, where respiratory paralysis is a potential hazard. An injectable calcium salt should be immediately available to counteract the potential hazards of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) intoxication in eclampsia.

50% Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Sulfate Injection, USP must be diluted to a concentration of 20% or less prior to intravenous infusion. Rate of administration should be slow and cautious, to avoid producing hypermagnesemia. The 50% solution also should be diluted to 20% or less for intramuscular injection in infants and children.

Laboratory Tests

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) is monitored. The normal serum level is 1.5 to 2.5 mEq/L.

Drug Interactions

CNS Depressants - When barbiturates, narcotics or other hypnotics (or systemic anesthetics), or other CNS depressants are to be given in conjunction with Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)), their dosage should be adjusted with caution because of additive CNS depressant effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)). CNS depression and peripheral transmission defects produced by Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) may be antagonized by calcium.

Neuromuscular Blocking Agents - Excessive neuromuscular block has occurred in patients receiving parenteral Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate and a neuromuscular blocking agent; these drugs should be administered concomitantly with caution.

Cardiac Glycosides - Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate should be administered with extreme caution in digitalized patients, because serious changes in cardiac conduction which can result in heart block may occur if administration of calcium is required to treat Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate can cause fetal abnormalities when administered beyond 5 to 7 days to pregnant women. There are retrospective epidemiological studies and case reports documenting fetal abnormalities such as hypocalcemia, skeletal demineralization, osteopenia and other skeletal abnormalities with continuous maternal administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate for more than 5 to 7 days.1-10 Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate injection should be used during pregnancy only if clearly needed. If this drug is used during pregnancy, the woman should be apprised of the potential harm to the fetus.

Nonteratogenic Effects

When administered by continuous intravenous infusion (especially for more than 24 hours preceding delivery) to control convulsions in a toxemic woman, the newborn may show signs of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate is an unapproved treatment for preterm labor. The safety and efficacy of such use have not been established. The administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate outside of its approved indication in pregnant women should be by trained obstetrical personnel in a hospital setting with appropriate obstetrical care facilities.

Nursing Mothers

Since Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) is distributed into milk during parenteral Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate administration, the drug should be used with caution in nursing women.

Geriatrics

Geriatric patients often require reduced dosage because of impaired renal function. In patients with severe impairment, dosage should not exceed 20 grams in 48 hours. Serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) usually are the result of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) intoxication. These include flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, cardiac and central nervous system depression proceeding to respiratory paralysis. Hypocalcemia with signs of tetany secondary to Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) intoxication is manifested by a sharp drop in blood pressure and respiratory paralysis. Disappearance of the patellar reflex is a useful clinical sign to detect the onset of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)).

For Treatment of Overdose

Artificial respiration is often required. Intravenous calcium, 10 to 20 mL of a 5% solution (diluted if desirable with isotonic sodium chloride for injection) is used to counteract effects of hypermagnesemia. Subcutaneous physostigmine, 0.5 to 1 mg may be helpful.

Hypermagnesemia in the newborn may require resuscitation and assisted ventilation via endotracheal intubation or intermittent positive pressure ventilation as well as intravenous calcium.

DOSAGE AND ADMINISTRATION

Dosage of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate must be carefully adjusted according to individual requirements and response, and administration of the drug should be discontinued as soon as the desired effect is obtained.

Both intravenous and intramuscular administration are appropriate. Intramuscular administration of the undiluted 50% solution results in therapeutic plasma levels in 60 minutes, whereas intravenous doses will provide a therapeutic level almost immediately. The rate of intravenous injection should generally not exceed 150 mg/minute (1.5 mL of a 10% concentration or its equivalent), except in severe eclampsia with seizures. Continuous maternal administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Solutions for intravenous infusion must be diluted to a concentration of 20% or less prior to administration. The diluents commonly used are 5% Dextrose Injection, USP and 0.9% Sodium Chloride Injection, USP. Deep intramuscular injection of the undiluted (50%) solution is appropriate for adults, but the solution should be diluted to a 20% or less concentration prior to such injection in children.

In Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) Deficiency

In the treatment of mild Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) (2 mL of the 50% solution) injected intramuscularly every six hours for four doses (equivalent to a total of 32.5 mEq of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) per 24 hours). For severe hypomagnesemia, as much as 250 mg (approximately 2 mEq) per kg of body weight (0.5 mL of the 50% solution) may be given intramuscularly within a period of four hours if necessary. Alternatively, 5 grams, (approximately 40 mEq) can be added to one liter of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP for slow intravenous infusion over a three-hour period. In the treatment of deficiency states, caution must be observed to prevent exceeding the renal excretory capacity.

In Hyperalimentation

In total parenteral nutrition, maintenance requirements for Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) are not precisely known. The maintenance dose used in adults ranges from 8 to 24 mEq (1 gram to 3 grams) daily; for infants, the range is 2 to 10 mEq (0.25 gram to 1.25 grams) daily.

In Pre-eclampsia or Eclampsia

In severe pre-eclampsia or eclampsia, the total initial dose is 10 grams to 14 grams of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate. Intravenously, a dose of 4 grams to 5 grams in 250 mL of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP may be infused. Simultaneously, intramuscular doses of up to 10 grams (5 grams or 10 mL of the undiluted 50% solution in each buttock) are given. Alternatively, the initial intravenous dose of 4 grams may be given by diluting the 50% solution to a 10 or 20% concentration; the diluted fluid (40 mL of a 10% solution or 20 mL of a 20% solution) may then be injected intravenously over a period of three to four minutes. Subsequently, 4 grams to 5 grams (8 to 10 mL of the 50% solution) are injected intramuscularly into alternate buttocks every four hours as needed, depending on the continuing presence of the patellar reflex and adequate respiratory function. Alternatively, after the initial intravenous dose, some clinicians administer 1 gram to 2 grams/hour by constant intravenous infusion. Therapy should continue until paroxysms cease. A serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) level of 6 mg/100 mL is considered optimal for control of seizures. A total daily (24 hr) dose of 30 grams to 40 grams should not be exceeded. In the presence of severe renal insufficiency, the maximum dosage of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate is 20 grams/48 hours and frequent serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) concentrations must be obtained. Continuous use of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Other Uses

In counteracting the muscle-stimulating effects of barium poisoning, the usual dose of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate is 1 gram to 2 grams given intravenously.

For controlling seizures associated with epilepsy, glomerulonephritis or hypothyroidism, the usual adult dose is 1 gram administered intramuscularly or intravenously.

In paroxysmal atrial tachycardia, Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) should be used only if simpler measures have failed and there is no evidence of myocardial damage. The usual dose is 3 grams to 4 grams (30 to 40 mL of a 10% solution) administered intravenously over 30 seconds with extreme caution.

For reduction of cerebral edema, 2.5 grams (25 mL of a 10% solution) is given intravenously.

Incompatibilities

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) sulfate in solution may result in a precipitate formation when mixed with solutions containing:

Alcohol (in high Heavy Metals

concentrations) Hydrocortisone sodium

Alkali carbonates and succinate

bicarbonates Phosphates

Alkali hydroxides Polymixin B sulfate

Arsenates Procaine hydrochloride

Barium Salicylates

Calcium Strontium

Clindamycin phosphate Tartrates

The potential incompatibility will often be influenced by the changes in the concentration of reactants and the pH of the solutions.

It has been reported that Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Citrate)) may reduce the antibiotic activity of streptomycin, tetracycline and tobramycin when given together.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Normal plasma Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) levels range from 1.5 to 2.5 mEq/liter.

As plasma Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) rises above 4 mEq/liter, the deep tendon reflexes are first decreased and then disappear as the plasma level approaches 10 mEq/liter. At this level respiratory paralysis may occur. Heart block also may occur at this or lower plasma levels of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)). Serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) concentrations in excess of 12 mEq/L may be fatal.

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) acts peripherally to produce vasodilation. With low doses only flushing and sweating occur, but larger doses cause lowering of blood pressure. The central and peripheral effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) poisoning are antagonized to some extent by intravenous administration of calcium.

Pharmacokinetics

With intravenous administration the onset of anticonvulsant action is immediate and lasts about 30 minutes. Following intramuscular administration the onset of action occurs in about one hour and persists for three to four hours. Effective anticonvulsant serum levels range from 2.5 to 7.5 mEq/liter. Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is suitable for replacement therapy in Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) deficiency, especially in acute hypomagnesemia accompanied by signs of tetany similar to those observed in hypocalcemia. In such cases, the serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) (Mg++) level is usually below the lower limit of normal (1.5 to 2.5 mEq/liter) and the serum calcium (Ca++) level is normal (4.3 to 5.3 mEq/liter) or elevated.

In total parenteral nutrition (TPN), Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate may be added to the nutrient admixture to correct or prevent hypomagnesemia which can arise during the course of therapy.

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is also indicated for the prevention and control of seizures (convulsions) in pre-eclampsia and eclampsia, respectively.

CONTRAINDICATIONS

Parenteral administration of the drug is contraindicated in patients with heart block or myocardial damage.

WARNINGS

FETAL HARM: Continuous administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate beyond 5 to 7 days to pregnant women can lead to hypocalcemia and bone abnormalities in the developing fetus. These bone abnormalities include skeletal demineralization and osteopenia. In addition, cases of neonatal fracture have been reported. The shortest duration of treatment that can lead to fetal harm is not known. Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate should be used during pregnancy only if clearly needed. If Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate is given for treatment of preterm labor, the woman should be informed that the efficacy and safety of such use have not been established and that use of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate beyond 5 to 7 days may cause fetal abnormalities.

ALUMINUM TOXICITY: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Parenteral use in the presence of renal insufficiency may lead to Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) intoxication. Intravenous use in the eclampsia should be reserved for immediate control of life-threatening convulsions.

PRECAUTIONS

General

Administer with caution if flushing and sweating occurs. When barbiturates, narcotics or other hypnotics (or systemic anesthetics) are to be given in conjunction with Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)).

Because Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) is removed from the body solely by the kidneys, the drug should be used with caution in patients with renal impairment. Urine output should be maintained at a level of 100 mL or more during the four hours preceding each dose. Monitoring serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) levels and the patient's clinical status is essential to avoid the consequences of overdosage in toxemia. Clinical indications of a safe dosage regimen include the presence of the patellar reflex (knee jerk) and absence of respiratory depression (approximately 16 breaths or more/minute). When repeated doses of the drug are given parenterally, knee jerk reflexes should be tested before each dose and if they are absent, no additional Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) should be given until they return. Serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) levels usually sufficient to control convulsions range from 3 to 6 mg/100 mL (2.5 to 5 mEq/liter). The strength of the deep tendon reflexes begins to diminish when Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) levels exceed 4 mEq/liter. Reflexes may be absent at 10 mEq magnesium/liter, where respiratory paralysis is a potential hazard. An injectable calcium salt should be immediately available to counteract the potential hazards of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) intoxication in eclampsia.

50% Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) Sulfate Injection, USP must be diluted to a concentration of 20% or less prior to intravenous infusion. Rate of administration should be slow and cautious, to avoid producing hypermagnesemia. The 50% solution also should be diluted to 20% or less for intramuscular injection in infants and children.

Laboratory Tests

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) is monitored. The normal serum level is 1.5 to 2.5 mEq/L.

Drug Interactions

CNS Depressants - When barbiturates, narcotics or other hypnotics (or systemic anesthetics), or other CNS depressants are to be given in conjunction with Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)). CNS depression and peripheral transmission defects produced by Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) may be antagonized by calcium.

Neuromuscular Blocking Agents - Excessive neuromuscular block has occurred in patients receiving parenteral Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate and a neuromuscular blocking agent; these drugs should be administered concomitantly with caution.

Cardiac Glycosides - Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate should be administered with extreme caution in digitalized patients, because serious changes in cardiac conduction which can result in heart block may occur if administration of calcium is required to treat Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate can cause fetal abnormalities when administered beyond 5 to 7 days to pregnant women. There are retrospective epidemiological studies and case reports documenting fetal abnormalities such as hypocalcemia, skeletal demineralization, osteopenia and other skeletal abnormalities with continuous maternal administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate for more than 5 to 7 days.1-10 Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate injection should be used during pregnancy only if clearly needed. If this drug is used during pregnancy, the woman should be apprised of the potential harm to the fetus.

Nonteratogenic Effects

When administered by continuous intravenous infusion (especially for more than 24 hours preceding delivery) to control convulsions in a toxemic woman, the newborn may show signs of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate is an unapproved treatment for preterm labor. The safety and efficacy of such use have not been established. The administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate outside of its approved indication in pregnant women should be by trained obstetrical personnel in a hospital setting with appropriate obstetrical care facilities.

Nursing Mothers

Since Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) is distributed into milk during parenteral Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate administration, the drug should be used with caution in nursing women.

Geriatrics

Geriatric patients often require reduced dosage because of impaired renal function. In patients with severe impairment, dosage should not exceed 20 grams in 48 hours. Serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) usually are the result of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) intoxication. These include flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, cardiac and central nervous system depression proceeding to respiratory paralysis. Hypocalcemia with signs of tetany secondary to Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) intoxication is manifested by a sharp drop in blood pressure and respiratory paralysis. Disappearance of the patellar reflex is a useful clinical sign to detect the onset of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)).

For Treatment of Overdose

Artificial respiration is often required. Intravenous calcium, 10 to 20 mL of a 5% solution (diluted if desirable with isotonic sodium chloride for injection) is used to counteract effects of hypermagnesemia. Subcutaneous physostigmine, 0.5 to 1 mg may be helpful.

Hypermagnesemia in the newborn may require resuscitation and assisted ventilation via endotracheal intubation or intermittent positive pressure ventilation as well as intravenous calcium.

DOSAGE AND ADMINISTRATION

Dosage of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate must be carefully adjusted according to individual requirements and response, and administration of the drug should be discontinued as soon as the desired effect is obtained.

Both intravenous and intramuscular administration are appropriate. Intramuscular administration of the undiluted 50% solution results in therapeutic plasma levels in 60 minutes, whereas intravenous doses will provide a therapeutic level almost immediately. The rate of intravenous injection should generally not exceed 150 mg/minute (1.5 mL of a 10% concentration or its equivalent), except in severe eclampsia with seizures. Continuous maternal administration of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Solutions for intravenous infusion must be diluted to a concentration of 20% or less prior to administration. The diluents commonly used are 5% Dextrose Injection, USP and 0.9% Sodium Chloride Injection, USP. Deep intramuscular injection of the undiluted (50%) solution is appropriate for adults, but the solution should be diluted to a 20% or less concentration prior to such injection in children.

In Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) Deficiency

In the treatment of mild Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) (2 mL of the 50% solution) injected intramuscularly every six hours for four doses (equivalent to a total of 32.5 mEq of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) per 24 hours). For severe hypomagnesemia, as much as 250 mg (approximately 2 mEq) per kg of body weight (0.5 mL of the 50% solution) may be given intramuscularly within a period of four hours if necessary. Alternatively, 5 grams, (approximately 40 mEq) can be added to one liter of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP for slow intravenous infusion over a three-hour period. In the treatment of deficiency states, caution must be observed to prevent exceeding the renal excretory capacity.

In Hyperalimentation

In total parenteral nutrition, maintenance requirements for Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) are not precisely known. The maintenance dose used in adults ranges from 8 to 24 mEq (1 gram to 3 grams) daily; for infants, the range is 2 to 10 mEq (0.25 gram to 1.25 grams) daily.

In Pre-eclampsia or Eclampsia

In severe pre-eclampsia or eclampsia, the total initial dose is 10 grams to 14 grams of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate. Intravenously, a dose of 4 grams to 5 grams in 250 mL of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP may be infused. Simultaneously, intramuscular doses of up to 10 grams (5 grams or 10 mL of the undiluted 50% solution in each buttock) are given. Alternatively, the initial intravenous dose of 4 grams may be given by diluting the 50% solution to a 10 or 20% concentration; the diluted fluid (40 mL of a 10% solution or 20 mL of a 20% solution) may then be injected intravenously over a period of three to four minutes. Subsequently, 4 grams to 5 grams (8 to 10 mL of the 50% solution) are injected intramuscularly into alternate buttocks every four hours as needed, depending on the continuing presence of the patellar reflex and adequate respiratory function. Alternatively, after the initial intravenous dose, some clinicians administer 1 gram to 2 grams/hour by constant intravenous infusion. Therapy should continue until paroxysms cease. A serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) level of 6 mg/100 mL is considered optimal for control of seizures. A total daily (24 hr) dose of 30 grams to 40 grams should not be exceeded. In the presence of severe renal insufficiency, the maximum dosage of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate is 20 grams/48 hours and frequent serum Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) concentrations must be obtained. Continuous use of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Other Uses

In counteracting the muscle-stimulating effects of barium poisoning, the usual dose of Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate is 1 gram to 2 grams given intravenously.

For controlling seizures associated with epilepsy, glomerulonephritis or hypothyroidism, the usual adult dose is 1 gram administered intramuscularly or intravenously.

In paroxysmal atrial tachycardia, Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) should be used only if simpler measures have failed and there is no evidence of myocardial damage. The usual dose is 3 grams to 4 grams (30 to 40 mL of a 10% solution) administered intravenously over 30 seconds with extreme caution.

For reduction of cerebral edema, 2.5 grams (25 mL of a 10% solution) is given intravenously.

Incompatibilities

Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) sulfate in solution may result in a precipitate formation when mixed with solutions containing:

Alcohol (in high Heavy Metals

concentrations) Hydrocortisone sodium

Alkali carbonates and succinate

bicarbonates Phosphates

Alkali hydroxides Polymixin B sulfate

Arsenates Procaine hydrochloride

Barium Salicylates

Calcium Strontium

Clindamycin phosphate Tartrates

The potential incompatibility will often be influenced by the changes in the concentration of reactants and the pH of the solutions.

It has been reported that Cal-Mag; Vitamin D; Zinc (Magnesium (Magnesium Oxide)) may reduce the antibiotic activity of streptomycin, tetracycline and tobramycin when given together.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Zinc (Zinc Citrate):


INDICATIONS AND USAGE

Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for TPN. Administration helps to maintain Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) is contraindicated as the acidic pH of the solution (2) may cause considerable tissue irritation.

Severe kidney disease may make it necessary to reduce or omit chromium and Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) doses because these elements are primarily eliminated in the urine.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless the solution is clear and the seal is intact.

Zinc 1 mg/mL should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Zinc should not be given undiluted by direct injection into a peripheral vein because of the likelihood of infusion phlebitis and the potential for increased excretory loss of Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) from a bolus injection. Administration of Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) in the absence of copper may cause a decrease in serum copper levels.

Laboratory Tests

Periodic determinations of serum copper as well as Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) are suggested as a guideline for subsequent Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) administration.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Cal-Mag; Vitamin D; Zinc ) 1 mg/mL (Zinc Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) is administered to a nursing woman.

Pediatric Use

Pregnancy Category C. Animal reproduction studies have not been conducted with Cal-Mag; Vitamin D; Zinc ) chloride. It is also not known whether Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) chloride should be given to a pregnant woman only if clearly needed.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Single intravenous doses of 1 to 2 mg zinc/kg body weight have been given to adult leukemic patients without toxic manifestations. However, acute toxicity was reported in an adult when 10 mg Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) was infused over a period of one hour on each of four consecutive days. Profuse sweating, decreased level of consciousness, blurred vision, tachycardia (140/min), and marked hypothermia (94.2° F) on the fourth day were accompanied by a serum Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) concentration of 207 mcg/dl. Symptoms abated within three hours.

Hyperamylasemia may be a sign of impending Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) overdosage; patients receiving an inadvertent overdose (25 mg zinc/liter of TPN solution, equivalent to 50 to 70 mg zinc/day) developed hyperamylasemia (557 to 1850 Klein units; normal: 130 to 310).

Death resulted from an overdosage in which 1683 mg Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) was delivered intravenously over the course of 60 hours to a 72 year old patient.

Symptoms of Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) level of 4184 mcg/dl.

Calcium supplements may confer a protective effect against Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) toxicity.

DOSAGE AND ADMINISTRATION

Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) 1 mg/mL (Zinc Chloride Injection, USP) contains 1 mg zinc/mL and is administered intravenously only after dilution. The additive should be diluted prior to administration in a volume of fluid not less than 100 mL. For the metabolically stable adult receiving TPN, the suggested intravenous dosage is 2.5 to 4 mg zinc/day (2.5 to 4 mL/day). An additional 2 mg zinc/day (2 mL/day) is suggested for acute catabolic states. For the stable adult with fluid loss from the small bowel, an additional 12.2 mg zinc/liter of small bowel fluid lost (12.2 mL/liter of small bowel fluid lost), or an additional 17.1 mg zinc/kg of stool or ileostomy output (17.1 mL/kg of stool or ileostomy output) is recommended. Frequent monitoring of Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Cal-Mag; Vitamin D; Zinc (Zinc (Zinc Citrate)).

For full term infants and children up to 5 years of age, 100 mcg zinc/kg/day (0.1 mL/kg/day) is recommended. For premature infants (birth weight less than 1500 g) up to 3 kg in body weight, 300 mcg zinc/kg/day (0.3 mL/kg/day) is suggested.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
